WinMD API Search

This skill helps you find the right Windows API for any capability and get its full details. It searches a local cache of all WinMD metadata from:

• Windows Platform SDK — all Windows.* WinRT APIs (always available, no restore needed)
• WinAppSDK / WinUI — bundled as a baseline in the cache generator (always available, no restore needed)
• NuGet packages — any additional packages in restored projects that contain .winmd files
• Project-output WinMD — class libraries (C++/WinRT, C#) that produce .winmd as build output

Even on a fresh clone with no restore or build, you still get full Platform SDK + WinAppSDK coverage.

When to Use This Skill

• User wants to build a feature and you need to find which API provides that capability
• User asks "how do I do X?" where X involves a platform feature (camera, files, notifications, sensors, AI, etc.)
• You need the exact methods, properties, events, or enumeration values of a type before writing code
• You're unsure which control, class, or interface to use for a UI or system task
